    What is a cool bag?

    A cool bag is a container primarily designed to store food. Cool bags are manufactured from a number of materials and technologies, designed to help maintain the temperature of their contents for as long as possible. Available in sizes all the way from individual lunch boxes all the way up to large electric cooling boxes.

    Top Tips for Choosing a Cool Bag

    Not all cool bags are created equal! Here's some top tips to help you choose a cool bag that fits your needs.

  • Insulation Time - A key indicator of the insulation on offer is the length of time the bag has been proven to maintain the temperature of it's contents for. Cool bags such as those in the Portal Outdoor Aspen range can boast a 5-7 hour insulation time.

  • Capacity - This is often measured in litres, and can range from just a handful, all the way up to 36 or more. Choose one that will fit your picnic in most adequately. A 12 Litre bag is more suited for a light lunch for a couple, where as a 36 Litre bag can easily hold lunch and cooled drinks for a whole family.

  • Straps and Fixing - Vital to the practicality of your cool bag are the straps included to carry it. Smaller cool bags such as the Aspen 12L bags offer an option to attach themselves to a bike's handlebars. For larger bags, such as the Aspen 36L bag, a strong padded over the shoulder strap provide a more suitable support for the weight.

  • Maximise Cooling Time - Want to keep your items colder for longer? Invest in a range of freezer boards, which can be inserted alongside your picnic to help it stay cooler, even on the hottest of days. Simply freeze the freezer boards overnight, and place inside the cool bag when packing it the next day.

  • Cleaning - Many cool bags have a foil lining on the inside. This is not always waterproof, so the best way to clean your cool bag is usually to use an antibacterial wipe to remove and debris and kill germs.

  • Multiple Compartments - Some cool bags now offer additional storage, which make them even more practical for your next picnic. The 12L Aspen cool bag for instance offers a see-through pocket on the top which can be used to secure your phone, keys or any other belongings.
